DANIEL GOFF, OF MILLVILLE, NEW JERSEY, ASSIGNOR TO GOFF GRAVITY BOILERFEED COMPANY, A CORPORATION OF NEW JERSEY.

BOILER-FEED.

To all whom it may concern:

Be it known that I, DANIEL Gorr, a citizen of the United States,residing at Millville, county of Camden, State of New Jersey, haveinvented a new and useful Boiler- Feed, of which the following is aspecification. I

My invention relates to a boiler feed, and consists of means forsupplying water to boilers and utilizing the steam from the boilers toforce the water thereinto.

It further consists of a novel controller which is adapted to besuitably actuated to allow the water to enter tanks or reservoirs and tosupply steam from the boilers into said tanks to force the watertherefrom into the boiler.

It further consists in providing valves, which are suitably actuated inorder to permit the entrance of steam into the tanks for forcing thewater therefrom and after the water has been forced therefrom, to permitexhaust of the steam from the tanks.

It further consists in providing a condenser for the exhaust steam.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

I have found in practice that it is essential to have water properly fedto boilers and in the drawings I have shown a construction of a boilerfeed which I have found operates successfully in practice and as showingan embodiment of my invention, but I desire it understood that changesmay be made in the construction, the arrangement of the parts may bevaried and other instrumentalities may be employed, which will comewithin the scope of my invention, and I do not therefore desire to belimited in every instance to the exact form as heretofore shown anddescribed, but desire to make such changes as may be necessary.

As previously stated, I desire to supply water to a plurality of tanksor reservoirs, the supply of water being controlled by valves in eachtank, so that supply of water will be cut off at the proper time. I alsodesire to employ the steam from the boiler to force the ater from thesetanks into the boilers and I have provided on each of the tanks valveswhich are suitably actuated by a controller, in order that the steamwill be directed or conducted into the tanks, at the proper time, toforce the water therefrom and will then be cut off and exhausted fromthe tanks.

I have provided controller which is supplied with water from the samesource as the tanks, the supply of water being properly controlled and Ialso conduct the steam from the boilers to the controller in order toforce the water from the controller suitably directing the steam toactuate the valves of the tanks to permit the steam to enter the saidtanks.

In the construction shown in Fig. 1, I have shown four boilers and fourtanks, it being understood that the two tanks on one side, that is theright of the figure, are arranged to be supplied with water, while thetwo tanks on the left of the figure are being supplied with steam toforce the water therefrom, although this may not be necessary in everyinstance and I may employ a single tank or any number, as may bedesired.

1 designates a plurality of boilers in the present instance, althoughone or any other number may be employed and I desire to utilize thesteam' from the boilers to force water from a suitable supply into theboilers.

2 designates a supply pipe leading from any suitable source throughwhich water is fed in a suitable condenser or heater 3.

4 designates a pipe leading from the condenser through which the waterpasses from the condenser, said pipe 4 having a branch leadingtherefrom, a branch 6 leading therefrom, a branch 7 leading therefromand a branch 8 leading therefrom, said branches each communicating witha tank or receptacle 9 whereby it will be understood hat water will passthrough pipe 4 and through the various branches into the said tanks atthe proper time. Leading from each of the tanks is a pipe 10 whichcommunicates with the pipe 11 suitably connected by branches 12 witheach of the boilers. Also communicating with the pipe 4 is a. branch orwater inlet pipe 13 which carries the water to a suitable controller 14as will be hereinafter described, it being understood, however, that apipe 15 is in suitable connection with said controller and is adapted toconductwater therefrom back to the pipe 11 and thence into the boi ersat the proper time. In order to conduct the steam fro-1n the boilers, toforce the water from the tanks 9 and controller 14 I provide a branch 16leading from each of the boilers which branches communicate with a pipe17, from which leads a pipe 18, which, by means of a pipe 19communicates with the controller 14 as will be hereinafter described,and which pipe 19 is provided with a branch 20 leading therefrom andconnecting with a pipe 21, from which leads branches 22 each of whichcommunicate with the interior of a tank 9, which branches 22 areproperly controlled by valve mechanism as will be hereinafter describedwhereby it will be un derstood that as steam passes through the branches16 into pipe 17 it will be directed into the pipe 18 and through pipe 19into the controller and will also pass through the branch 20 into thepipe 21 from thence it will pass through the branches or pipes 22 toproperly enter the tanks 9, it being understood that the controllerprovides for the proper admission of the steam into the tanks 9, inorder to force the water therefrom through the branches 10, pipe 11 andbranches 12 into the boilers.

The water from the condenser 3 is directed through the pipe 4 and intothe pipe 13 which is provided with a suitable check valve 23, see Fig.6, so positioned as to allow the passage of the water therethrough inthe direction indicated by the arrow in Fig. 6 and the water will passthrough the pipe which is in suitable connection with the pipe 13 andwill be directed into a tank 24 which forms part of the controller andwhich pivotally mounted to oscillate, as will be hereinafter described,it being noted that the said pipe 25, in the present instancecommunicates with the interior of the tank 24 through the trunnion 26,see Fig. 12, on one side of the tank 24. The pipe 13 is also providedwith a valve 27 which is in suitable connection with the tank 24 inorder to be opened and closed by the rocking thereof, as will behereinafter described, and said valve 27 is open when the tank 24 is inits elevated position, as seen in Figs. 3 and 4, 8 and 9. After asutlicient quantity of water has been received in the tank 24 the weightof the water therein will overcome the weights 45 which are suitablyconnected with said tank 24 at which time the lever will turn with itstrunnions 26 and 49 that are in suitable communication therewith in thedirection indicated by the arrow (6 in Fig. 8. At the same time thevalve 27 which is in suitable communication with the tank 24 by means ofthe lever 82 and link 83 will be closed and thus cuts off a furthersupply of water to the tank 24. Suitably connected with the tank 24 isan arm 30 which in the present instance serves to support the weights 45and connected with the arm 30 is a link 28 to which is suitablyconnected a link 29 the lower end of which is pivotally connected to thecylinder 31 upon one side of its pivot 32*, whereby it will beunderstood that as the tank 24 lowers, the end of the cylinder 31, withwhich the link 29 is connected, will be elevated by reason of theelevation of the arm 30 and the opposite end of the cylinder 31 will belowered in the direction indicated by the arrow 6 in Fig. 8.

32 designates a weight or ball freely movable in the said cylinder 31and as the cylin der 31 is rocked by the movement of the tank 24, theball will be caused to move from its position seen in Fig. 8 to thatseen in Fig. 10 and thus insure the proper rocking movement of the tank24. Connected with the cylinder 31 upon the opposite side of its pivotalpoint 32 is a link 33 which is connected with a lever 34 on one side ofits fulcrum the opposite end of said lever 34 having a link 36 connectedtherewith which is connected with the lever 37, which is pivoted at 46to a suitable stationary point, while connected to said lever 37 is avalve 38 which controls or is suitably situated in the pipe 19, in orderto control the passage of steam from said pipe into the controller andas the position of the cylinder 31 is changed from that seen in Fig. 8,it will be understood that through the medium of the link 33, lever 34,link 36 and lever 37 the valve 38 will be opened and steam from theboilers 1 flowing through pipes 16, 1S and 19 is directed through thevalve 38 into the pipe 39 and then through the trunnion 49 and wherebyit will be understood that suitable steam pressure is exerted on thewater within the tank 24; and casing 40 to force.

water therefrom. As the tank 2st and its adjuncts are located above theboilers, it will be understood in addition to pressure of the steamwithin the tank and easing, the force of gravity or weight of the waterflowing from the tank and easing, overcomes the pressure in the boilers1 and opens the valve 13, see Fig. 5, which is situated in the pipe 15,which leads from the pipe 25 and communicates with the pipe 11 which isin communication with the branches 12, so that the water will passthrough these pipes into the boilers against the back pressure of steamfrom said boilers, it being understood that the valve 43 in the pipe 15is closed under normal conditions by steam pressure from the boilers 81which is exerted in the direction indicated by the arrow 0 in Fig. 6. Itwill be noted that the branches 12 are each provided with a checkvalve14: to prevent backward flow of water from said boilers 1 but whichpermit passage of water into the boilers. When the valve 13 is openedthe pressure of the water from the tank 24 and cas ing 40 will serve tohold the valve 23 in the pipe 13 closed so that water cannot pass inthat direction but must flow to the boilers. From the above it will beunderstood that I have directed water from the condenser 3 into the tank24: in order to lower the same and have conducted steam from the boilerinto said tank 241 to force the water therefrom into the boiler 1, itbeing of course understood that water in the meantime has been fed intothe two tanks 9 at the right, as seen in Fig. 1 and I now desire tointroduce steam from the boilers into these two tanks 5) in order toexert a pressure therein to force the water therefrom. hen the valve 38is opened as hereinbefore described, in addi tion to directing the steamfrom the boilers 1 into the casing 40 and tank 24 it will be understoodthat some of the steam is directed through pipe 47, which is incommunication with the pipe 39 into the branch pipes 418, each of whichdischarges into a suitable cylinder 50, carried by the tan s 9 in anysuitable manner, as will be best understood from Fi s. 1 and 13, andwill operate the piston 89 in each of said cylinders to elevate thesame. The pist on S9 is con nected with the weighted lever 90 pivoted at91 to a suitable stationary point, the other side of said lever beingconnected with a le ver 93 which is in suitable communication with avalve 63 which controls the pipe 22 which it will be understood is incommunication with the boilers 1 and is conducting steam therefrom. Whenthe piston 89 is elevated the valve 63 is opened and steam is permittedto enter the two tanks 9 to the right as seen in F 1 and forces thewater therefrom through pipes 10 into the pipe 11 and through branches12 into the boilers 1. Get designates a second valve adjacent the firstvalve 63 which is in suitable connection with a lever 92, pivotallysupported at 9 1 and which is in suitable connection with the weightedlever 90 in such a manner that the said valve 64: is closed when thevalve 63 is opened and vice versa.

lVhen the tank 2 1- and casing 40 are emptied of water, as previouslydescribed, the weights 15 will act to raise the tank 2 1 and by reasonof this the links 28 and 29 are lowered and also the end of the cylinder31 in the position seen in Fig. 8 which thus through the medium 01'' thelinks 33, lever 34, link 36 and lever 37 actuates the valve 38 to closethe same thus cutting off the supply of steam which is exerted beneaththe piston 89, and the weighted end of the lever 90 always will fall,closing the valve 63, on the two tanks to the right in Fig. 1 andopening the valves 64, immediately upon which the steam in the two tankscan exhaust from the pipe 62 in communication with the valve 6 1 andwill be directed into the pipe 57 which is in communication with. thecoil 58 in the condenser 3 and will pass through pipe 59 and be directedinto the interior ot' the condenser 3, as will be understood from Fig.2, it being noted that the pipe 59 is provided with the check valve 60to prevent water in the condenser from entering the coil pipes 53, whilethe pet cock (31 is provided, which, when opened, will permit thecondensed steam in the coil to escape therefrom. Also connected with thecylinder 31 is a link 67 which is connected with a lever 68 pivoted at69, which is in suitable connection with a link 70 connected with oneend of the lever 71 pivoted at 72, said lever being in suitablecommunication with a valve 55, suitably positioned with respect to thevalve 38 and connected in such a i'i'ianner by reason of the pivotalpoint of the lever 71, that when the cylinder 31 is rocked when onevalve is opened the other is closed, whereby it will be understood thatas the tank 24 is elevated after having been emptied of water thecylinder 31 is rocked in order to open the valve and the steam from theinterior of the tank 24 and easing 4-0 will exhaust through the pipe 39and valve into the pipe which is controlled by said valve and will bedirected into the pipe 57 and thus into the coil 58 as previouslydescribed with respect to the exhaust from the two tanks 9, while thesteam from the pipes 457 and 4S and the cylinders will likewise exhaustas the pipe 17 is in communieation with the pipe 39. Connected with thelever 71 at 73 is a bar or rod 71, which connected with a two-way valve75 which controls the pipe 51 which is in communication with the branchpipe leading from the pipe 21, said pipe having branches therefrom, eachcommunicating with a cylinder similar to the cylinders 50, saidcylinders 53 being respectively mounted on the tanks 9 at the left ofFig. l and said cylinders each having a piston 89 similar to thatalready described, the rest of the operating parts being the same asthat described with respect to the two tanks at the right of Fig. 1 andit is deemed unnecessary to describe these tanks and operating parts, itbeing understood that as the lever 71 is operated to open the valve itwill at the same time operate the valve 75 to open'the pipe 51 to thepipe 54:, whereupon as steam passes through the pipe 51 and branches 52to the cylinders of the two tanks to the left in Fig. 1, so that thepistons 89 thereof are properly actuated to open the valves 63 on saidtanks and steam from the pipes or branches 22 will pass into these tanksand force the water therefrom through pipes 10 into the pipes 11 andthrough the branches 12 into the boilers 1 whereby it will be understoodthat these tanks will be emptied. It will be understood that as soon asthe tank 2% is rocked again the lever 71 is 0perated to close the valve75 so that the steam from the cylinders 53 and pipes 01 and can exhaust,at which time the valves 63 are closed and the valves 64: opened, on thetanks on the left hand of Fig. 1 so that the steam therefrom can exhaustthrough the pipes (32 and into the coil 58 to the condenser 3. I11 themeantime, water has been permitted to flow into the tanks 9 at the rightof Fig. 1, the amount of water in each of the tanks being controlled bya float 66, each of the tanks 9 being supplied with a float and each ofwhich is in suitable communication with a. valve 65, each of thebranches 5, 6, 7 and 8, through which water is conducted, being providedwith a valve, so that when the float (S6 is elevated to the proper levelin a tank 9 the further supply of water is cut off. Immediately that thetank 24 is elevated the valve 27 opened again and water is againpermitted to flow into the tank 2% as previously described and lower thesame again, the operation of the parts being similar to that already setforth as above. In order to prevent the steam in the tanks 9 fromforcing water back through the various branches in the condenser 3, Ihave provided the branch 8 and check valve 98 in branch 0 and checkvalve 101 and in the branch 5, check valve 100 which will serve toprevent improper movement of the water. I also provide suitable checkvalves 96 in the branches 10 to prevent the water from coming from theboilers back into the tanks ter which is fed to the boilers withsuitable" boiler compound and I have shown in Fig. at a tank 77 which isadapted to receive the compound. Leading from the steam supply pipe 39is a pipe 76 which conducts steam from said pipe 39 and discharges thesame into the upper portion of the tank 77, a suitable valve 79 beingsituated in pipe to prevent steam from backing up.

78 designates a pipe leading from the tank 77 and communicating withpipe 15 so that the boiler compound will be discharged into the water asit passes through pipe 15 and is directed into the boilers. In said pipe78 I provide a valve 81 which can be suitably regulated to supply therequisite amount of boiler compound to the water and I also provide avalve 80 which will prevent water from backing up and being forced intothe tank 77 as will be evident. I desire it understood that the partsmay be supported in any desired or suitable manner and in the drawings Ihave shown rollers 102 which support the trunnions 26 and 49 of the tank24 and its adjuncts, said rollers in the present instance beingsupported on the frame 103, which supports the controller.

T ie operation is as follows :Assuming the several parts of this deviceto be in the positions indicated in the drawings, water from asuitablesource of supply flows through the pipe 2 and passing through the cock97 enters the condenser or heater 3 and passes therefrom through thepipe a and is directed thereby to the branch pipe 8 and passing throughthe check valve 98 enters the tank 9 at the righthand end of the seriesof tanks 9 seen in Fig. 1, until the float 66 in said tank is raised toclose the valve 65. The water in the pipe s also enters the branch pipe7 and passing through the check valve 99 enters the tank 9, that is, incommunication with the branch 7 until the proper height of water isreached. The water in the pipe 4 also enters the branch pipe 13 andpassing through the check valve enters the tank 2e and the water fromthe pipe 4 also enters the branches 5 and (3 and passing through theirrespective check valves 100 and 101 enters the tanks 9 to the properheight.

IVhen the weight of the water within the tank 24, as fed thereto fromthe condenser 3, exceeds that of the weights 45 and the ball 32 saidtank turns on its trunnions 26 and L9 and in the direction indicated bythe arrow a in Fig. 8.

The tank 24 in moving in the direction i11- dicated by the arrow adepresses the arm 82 and link 83, thus closing the valve 27 and shuttingoff the supply of water from the condenser 3 to the tank 24:.

The downward movei'nentof the tank 24 elevates the arm 80, links 28 and29, cans ing the cylinder 81 to move in the direction indicated by arrowZ) in Fig. 8, which open the valve 38 and closes the alve Steam from theboilers passes through the branches 16, pipe 1'? and pipe 18, to thepipe and 21 and through the branches is stopped by the valves (33 untilopened. as hereinafter described. Steam is also in the pipe 19 and whenthe valve 38 is opened as described, the steam passes thence to thepipes 39, 4-1. and 4:2 and discharges into the tank 24, and casing so asto exert a downward pressure on the water within said tank causing it totlow therefrom through check valve 43 and pipes 15, 1.1 and 12'and checkvalves 1-4: and dipcharge into the boilers 1. it is to be u1'iderstoodthat the water as forced through the pipes 11 and 10 by the controller 1cannot enter the tanks 9 on account of the check valves 96. Steam fromthe boilers 1 passing through the open valve 38 also tlows through thepipes 39, 47 and l8 and enters the cylinders 50 thus elevating thepiston 89 therein so as to turn the lever 90 on its fulcrum 91 as willbe understood from Figs. 1 and 13.

The turning of the lever 90, due to the upward movement of the piston89. operates the levers J2 and 93 so as to open the valves 63 and closethe valves l-t that cooperate with the tanks 5) that are supplied with'ater through the branch pipes 7 and 8. that is the two tanks 9 to theright in Fig. 1.

Steam from the boilers 1 after passing through the pipes 16, 18, 20, 21and 2:2 reaches the valves (33 and since said valves 3 that cooperatewith the tanks 9 are supplied with water by the pipes T and S are open,as hereinbetore described, live steam passes through the same and enterstheir respective tanks 9 so as to exert a dmvnward pressure on the waterwithin said tanks and force the water theretron'i through the valves 96and pipes 10 to the pipes 11 and 12 and finally through the check valves44 into the boilers 1.

It is to be understood that steam in branches 22 cannot pass through thevalves 63 that cooperate with the tanks 9 as supplied with water throughthe branches 5 and 6, that is the two tanks to the left in Fig. 1. onaccount of their being closed when the tank 24L- is in its loweredposition.

When the water has been discharged from the tank 2 1 the weights returnsaid tank to its elevated position as seen in Fig. 8, it beingunderstood that in doing this said tank 2 1 turns with its trunnions 26and 49 on the rollers 102 and in a direction opposite to that indicatedby the arrow a. The upward movement of the tank 24; closes the valve 38and shuts otl the supply of steam to said tank 2% and also to thecylinders 50 that cooperate with the tanks 9 fed with water through thebranches 7 and 8.

As soon as the pressure is released in the cylinders 50 the pistons 89fall or lower carrying with them the end of the lever 90 which actuatesthe lever 98 to close the valve 63 so that no further steam is permittedto enter the tanks 9 to the right of Fig. 1 and the valve Get, howeveris opened permitting the exhaust of the steam from these tanks 9 throughpipes 62 back into the condenser. In the meantime, the water having beenforced from said tanks 9 the float valves 66 therein are lowered inorder to open the valves and the ater will again be directed in thesetanks to the proper height.

\Vhen the tank has reached its elevated or normal position seen in Fig.7, it opens the *alve by reason of the lowering of the arm 30 thatcooperates with the link 28. link 29, cylinder 31, link (37, lever (38,link and lever '71, connected with said valve as will be understood fromFig". at.

As soon as the valve 55 is opened the steam within the tank 24- escapestherefrom through the pipes 42, 41, and valve and passing through thepipes 56 and 57 enters the coil 58 as exhaust steam and dischargesthrough the pipe 59 into the condenser 3.

hen the tank 24: is in. its elevated position, in addition to openingthe valve 55 it also opens the valve '75 which as hereinbetore describedis a. two-way valve. The opening of the valve '75 accomplished throughthe lever 71 and rod 74, as will be understood from Fig. 7

hen the valve 75 is open the steam from the pipe 21 passes through thepipe 54 to the pipe 51 and to the cvlinders and thus on the underside ofthe piston 89, which elevates the pistons therein and so opens thevalves 63 and the steam from the pipes 22 passes into the tanks 9 at theleft in Fig. 1 and forces the water into the boilers 1. When the tank 24lowers again. the valve 75 is actuated to close the communication withthe pipe 54- and open the pipe 51 to exhaust to the atmosphere. Thiscauses the piston 89 to lower and in so doing operates the levers 90. 92and 93 so as to close the valves 63 and open the valves 64: thatcooperate with the tanks 9 as supplied with ater by the branch pipes 7and 8. lVhen said valves 63 are closed the supply of steam to theirreceptive tanks 9 is shut ofii while at the same time the opening of thevalves 64: permits the steam within said tanks to escape therethroughand flowing through the pipes 62 and 57 enters the coil of pipe 58 inthe condenser 3.

It is apparent from the foregoing description that when the two tanks 9on the right of the controller 1 1 in Fig. l are filling with water, thetwo tanks 9 on the left of said controller let are discharging waterinto the boilers l and vice versa.

The controller ltk is provided with a registering device 105 of any wellknown description, seen in Figs. 5 and 11, that is adapted to indicatethe number of oscillations of the tank 24 in a given time, it beingobserved that said registering device is operated by the lever 71.
